In this paper, we considered a silicon solar cell with some ribbon nanoparticles including silver (Ag), aluminum (Al), gold (Au), and platinum (Pt) ribbon nanoparticles. The dimensions of nanoparticles affect the absorption and efficiency of solar cells. Here, various dimensions were examined, and the width, height, and period of the ribbon nanoparticle were taken into account. In this paper, we investigated the effect of height, width, period, and materials of ribbon nanoparticles by finite-difference time-domain method. The simulation results show that the maximum absorption was obtained equal to 12.90% by using the silver ribbon nanoparticles having width (x) of 25 nm, height (h) of 50 nm, and period (p) of 50 nm. In this case, the fill factor was obtained as 81.31%.
